BS 3790:2006

If you design or manufacture belt drive equipment, you will need to be completely familiar with product types, availability and the latest specifications. A new edition of BS 3790 is now available - a full revision of the standard used by the power transmission industry.

This new publication is an essential standard for design and maintenance engineers of agriculture, paper making or automotive machines; and for mining, quarries, process industries and the power transmission industry.

What are the significant changes?

• Fully updated to reflect advances in industry and product.
• Adopts datum system of measurement.
• Banded belts, i.e. belts joined across the top surface, have been included.
• Now specifies anti-static data that is used to test anti-static belts.
• Linked to the ATEX Directive 94/9/EC requirements which are now European law.

Why do I need BS 3790?

• To comply with the ATEX Directive for potentially explosive atmospheres.
• To specify product that represents best practice in world markets.
• For the facilitation of free trade within the EU by aligning the technical and legal requirements for products.
• So purchasing organisations are able to specify a type of product in tender documents.
• It is the most comprehensive standard available as one document.

BS 3790:2006 specifies the dimensions and certain other properties of endless wedge belts, V-belts and equivalent banded belts and their corresponding grooved pulleys, when used for power transmission.

Recommendations and information on the design, selection and installation of drive assemblies are given in Annex C and Annex E. Recommendations on the storage of belts are given in Annex B.

This standard does not apply to industrial variable speed drives employing pulleys with movable flanges, or to drives specified in BS 3733 or BS ISO 5287.

BS 3790:2006 supersedes BS 3790:1995 which is now withdrawn.
